Description
Technical Field
The invention relates to the technical field of medical instruments, in particular to the technical field of connecting instruments for continuous peritoneal dialysis.
Background
Peritoneal dialysis is a method of treating severe chronic kidney disease. This therapy utilizes the peritoneum of the patient's abdomen as a membrane through which fluids and dissolved substances are exchanged with the blood. The dissolved substances include electrolytes, urea, glucose, albumin and other small molecules. When the patient sleeps or has a rest, the liquid is infused into the peritoneal dialysis solution through the permanent conduit on the abdomen to exchange solute and moisture with blood components in the capillary vessel on the other side of the peritoneum, so as to remove metabolites and excessive moisture retained in the body, and simultaneously supplement substances necessary for the body through the dialysis solution. Regular fluid changes throughout the day are called "continuous peritoneal dialysis," abbreviated CAPD. Peritoneal dialysis is available as an alternative to hemodialysis, but is less used in many countries. Its risk is comparable to hemodialysis, but the cost is significantly reduced. A major advantage of CAPD is that the patient can be treated without going to a hospital or doctor's operating room or the like. The major complication of peritoneal dialysis is infection due to the presence of a permanent catheter in the abdominal cavity.
